The tragicus, also called the tragus muscle or Valsalva muscle,[1] is an intrinsic muscle of the outer ear.
It is a short, flattened vertical band on the lateral surface of the tragus.[1]
While the muscle modifies the auricular shape only minimally in the majority of individuals, this action could increase the opening of the external acoustic meatus in some.[2]
